Endocarditis I: Introduction01:25

Endocarditis I: Introduction

867
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Endocarditis IV: Nursing Management

628
Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Endocarditis II: Clinical Features of Infective Endocarditis

919
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Endocarditis III: Medical Management

359
Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Bacterial Gastroenteritis

87
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Myocarditis I: Introduction01:21

Myocarditis I: Introduction

645
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Clinical Case Reports

Background:

  • Shewanella putrefaciens is an environmental bacterium rarely implicated in human infections.
  • Recent decades show a rise in reported cases of Shewanella putrefaciens-related human infections.
  • Infective endocarditis is a serious infection of the heart's inner lining.

Observation:

  • A case of infective endocarditis in a 40-year-old immunocompetent male is presented.
  • The infection was apparently caused by a single species, Shewanella putrefaciens.
  • This represents a rare instance of monomicrobial endocarditis due to this pathogen.

Findings:

  • This is the first reported case of infective endocarditis caused by an apparently monomicrobial Shewanella putrefaciens infection.
  • It is the second documented case of Shewanella putrefaciens-related infective endocarditis globally.
  • The findings highlight the potential pathogenicity of Shewanella putrefaciens in susceptible individuals.

Implications:

  • This case expands the understanding of Shewanella putrefaciens as a human pathogen.
  • It underscores the importance of considering environmental bacteria in diagnosing complex infections.
  • Further research is needed to elucidate the mechanisms and risk factors for Shewanella putrefaciens endocarditis.
